> Hi,
>
> A piece of my code that uses readBin() to read a certain file type is
> behaving strangely with R 2.7.0. This seems to be because of a failure
> to match() strings after using rawToChar() when the original was
> terminated with a "\0" character. Direct equality testing with ==
> still works as expected. I can reproduce this as follows:
>
> > x <- "foo"
> > y <- c(charToRaw("foo"),as.raw(0))
> > z <- rawToChar(y)
> > z==x
> [1] TRUE
> > z=="foo"
> [1] TRUE
> > z %in% c("foo","bar")
> [1] FALSE
> > z %in% c("foo","bar","foo\0")
> [1] FALSE
>
> But without the nul character it works fine:
>
> > zz <- rawToChar(charToRaw("foo"))
> > zz %in% c("foo","bar")
> [1] TRUE
>
> I don't see anything about this in the latest NEWS, but is this
> expected behaviour? Or is it, as I suspect, a bug? This seems to be
> new to R 2.7.0, as I said.
